BACKGROUND

The present disclosure generally relates to health and nutrition. More specifically, the present disclosure relates to nutritional compositions including exogenous vitamin K2 and methods of making and using the nutritional compositions.

There are many types of nutritional compositions currently on the market. Nutritional compositions can be targeted toward certain consumer types, for example, young, elderly, athletic, etc., based on the specific ingredients of the nutritional composition. Nutritional compositions can also be formulated based on the certain physiological conditions that the nutritional compositions are intended to treat or improve.

One goal of nutritional support is to improve bone health by increasing bone density and strength and reducing the incidence of fracture risk. Due to rapidly changing bone densities in children during normal growth and development, or due to underlying medical conditions, children may require nutritional compositions to improve indices of bone health and promote bone growth and bone quality.

DETAILED DESCRIPTION

Maintenance of bone health is essential for mobility and the bone matrix is an important reservoir for critical minerals. On average, 90 percent of peak bone mass is acquired by the age of 18 for women and 20 for men. As such, it is important to promote proper bone health and bone growth and bone quality during the period of normal growth and development in children prior to these ages. Given the accelerated rate of bone accretion during the adolescent period, providing essential nutrients ensures the optimal functioning of the bone formation process. Further, failure to promote bone mineral density during this critical period can lead to decreased bone strength and bone tissue microarchitecture, which can elicit the onset of fragility fractures in the pediatric population.

During childhood bones grow because resorption (the process of breaking down bone) occurs inside the bone while formation of new bone occurs on its outer (periosteal) surface. At puberty the bones get thicker because formation can occur on both the outer and inner (endosteal) surfaces. The remodeling process occurs throughout life and becomes the dominant process by the time that bone reaches its peak mass (typically by the early 20s). In remodeling, a small amount of bone on the surface of trabeculae or in the interior of the cortex is removed and then replaced at the same site. The remodeling process does not change the shape of the bone, but it is nevertheless vital for bone health. Modeling and remodeling continue throughout life so that most of the adult skeleton is replaced about every 10 years. While remodeling predominates by early adulthood, modeling can still occur particularly in response to weakening of the bone.

While Calcium and vitamin D are important nutrients for the development of the inorganic matrix of the bone, several nutrients are needed for normal development of the organic matrix of bone. Specifically, adequate vitamin K, and trace minerals such as zinc, copper, iron nutriture are required for the normal metabolism of noncollagenous proteins such as osteocalcin, osteopontin. Provision of these nutrients during rapid growth, can lead to prevention of osteomalacia and osteoporosis later in life. This improves quality of life and also will save healthcare costs related to hip fractures.

Vitamin K denotes a group of lipophilic, hydrophobic and essential vitamins having a common chemical ring structure (napthoquinone). The two most important forms of vitamin K are vitamin K₁, a single compound known as phylloquinone or phytomenadione, and vitamin K₂, a series of vitamers known as menaquinones or menatetrenones. There are also several synthetic forms of vitamin K including, for example, vitamins K₃, K₄ and K₅.

Vitamin K1 is the major form of vitamin K in a normal diet and is synthesized by plants including, for example, certain plant oils such as canola and soybean and in green leafy vegetables such as spinach, swiss chard, broccoli, cabbage, cauliflower, kale, and brussels sprouts.

Vitamin K₂ is a group of compounds called menaquinones (“MK”) having side chains composed of a variable number of unsaturated isoprenoid residues generally designated as MK-n, where n specifies the number of isoprenoids. The most common MKs are MK-4 and MK-7. MK-4 is typically synthesized by animal organs and muscle, while MK-7 is typically synthesized by bacteria during fermentation. Accordingly, MK-7 is particularly abundant in fermented products including cheese, curd cheese and natto (fermented soybeans) and has a particularly long half-life when compared to vitamin K₁.

The estimated average requirement for vitamin K in children ages 1 to 18 years in the United States is based upon median intakes of vitamin K for adults. These levels are designed to meet the vitamin K levels required for normal blood coagulation and not other vitamin K-dependent proteins such as osteocalcin. The ratio of under-carboxylated (i.e., inactive) to carboxylated osteocalcin can be a surrogate marker for vitamin K status. Recent evidence suggests that children between the ages of 6 and 18 years of age have elevated levels of undercarboxylated osteocalcin relative to adults. Rather than attempting to increase the intake levels via higher vitamin K₁ intake, vitamin K₂ allows for administration of a more potent form of vitamin K without negatively impacting parameters of anticoagulation.

As compared to vitamin K₁, vitamin K₂ provides better absorption and more stable serum levels through a longer half-life. The improved bioavailability of vitamin K₂ to extrahepatic tissue may also allow for a greater impact on bone health (i.e. mineralization, microarchitecture and strength) during normal growth and development. Therefore, vitamin K₂ provides for a more potent form of the vitamin in which its enhanced bioavailability can impact bone health during normal growth and development.

Additionally, there exists several medical conditions in which bone growth and bone quality in pediatric patients may be compromised. Such conditions may include, for example, developmental delay, failure-to-thrive, neuromuscular dysfunction, severe food allergy and inflammatory bowel disease (e.g., Crohns disease or ulcerative colitis). For example, the incidence of low bone mass in children having inflammatory bowel disease (“IBD”) ranges from about 30-50%. Vitamin K is a cited nutrition deficiency in this population and its limited bioavailability may reduce osteocalcin carboxylation as well as reduce bone strength, bone mineralization and bone microarchitecture. Accordingly, children suffering from any of the above-mentioned medical conditions may benefit from a more effective dose of vitamin K.

Rather than attempting to increase the intake levels via higher vitamin KI intake, Vitamin K2 allows for a more potent form of vitamin K without negatively impacting parameters of anticoagulation. Specifically, vitamin K2 provides better absorption and more stable serum levels through a longer half-life when compared to phylloquinones (vitamin K1). Improved bioavailability of vitamin K2 to extraheptic tissue may allow for a greater impact for improving musculoskeletal health in patients with inflammatory bowel disease (IBD) (Crohn's Disease and Colitis), especially pediatric patients. The incidence of low bone mass ranges from 30-50% in children with IBD. Vitamin K is a cited nutrition deficiency in this population and its limited availability may reduce osteocalcin carboxylation as well as reduce bone strength, bone mineralization and bone micro-architecture. In addition, a low vitamin K status may be a causative factor in Crohn's Disease-associated osteopenia. The osteopenia and elevated rate of bone resorption noted in some Crohn's Disease patients is a multifactorial process and vitamin K deficiency is certainly only one factor in this process. Low vitamin K levels can lead to an increase in the rate of bone resorption, without a compensatory increase in the rate of bone formation. An increased rate of bone turnover is associated with an increased risk of bone loss in Crohn's Disease patients. In terms of nutrition-related etiological factors for osteopenia, there are indications that in patients with longstanding Crohn's Disease, vitamin K deficiency has a greater influence on bone turnover than serum 25(OH) vitamin D concentrations. Vitamin K2 may serve as a critical micronutrient for optimizing bone regulation in this target population.

Further, vitamin K₂ may also be effective for bone health in pediatric patients undergoing concurrent drug treatments including, for example, corticosteroids, bisphosphonates or anti-coagulative drugs. Similarly, pediatric patients undergoing biologic therapies or having conditions of gastrointestinal (“GI”) impairment including, for example, short bowel syndrome, ulcerative colitis, celiac disease, cystic fibrosis, renal dysfunction and androgen deficiency, gluten intolerance, Crohns disease or severe allergy, may also benefit from administration of nutritional compositions having exogenous vitamin K₂.

Applicant has surprisingly found that administering exogenous vitamin K₂ as part of a nutritional formulation will improve osteocalcin carboxylation and improve indicies of bone health during normal growth and development in children. Additionally, vitamin K₂ supplementation can also promote bone growth and bone quality in pediatric patients with underlying medical conditions in which bone growth and bone quality may be compromised. As a result, Applicant has found that administration of exogenous vitamin K₂ increases bone density and improves bone tissue microarchitecture in pediatric patients, thereby reducing the incidence for fracture risk. The effects of vitamin K₂ may be seen directly on bone quality such that this form of vitamin K modulates formation of proteins in the organic matrix of the bone involved in microarchitectural morphology, mineralization, density, elasticity and mechanical stiffness, as measured by peripheral quantitative computer tomography (“pQCT”) or Dual Energy X-ray absorptiometry (“DEXA”). Vitamin K₂ may also be effective for bone health in patients undergoing concurrent drug treatment.

Generally speaking, bone density is expressed as the relationship between bone mass (expressed as the degree of photon attenuation through the bone, or bone mineral content (BMC)) and the image of the bone on a film (i.e., the area) (expressed as BMC/em²). Additionally, pQCT is a procedure that evaluates peripheral bone in 3 dimensions (volumetric) and is commonly applied to the forearm or tibia. A radiation source (typically x-rays) and a sensor revolve around the bone under examination, which is them reconstructed on the computer screen in a three-dimensional (3-D) image. pQCT is an optimal technique for evaluating bone geometry even though sensitivity varies with the site under evaluation. Unlike most other techniques, pQCT measures true bone density (volumetric mineral bone density) because it normalizes the bone mineral content derived not from the projected area but rather from the volume of the examined bone. pQCT can also be used to calculate the SSI, an index of bone resistance to torsion. The index takes into account bone geometry and the bone's mineral characteristics. See, Geometry and bone density, Radetti, G., et al., Panminerva Med 2006; 48:181-6.

DEXA is based on x-ray spectrometry and it's fundamental principle is based on the degree of attenuation of x-rays emitted from 2 different sources of energy. DEXA is normally used to evaluate lumbar or proximal femoral bone mineralization. DEXA has an accuracy of 4-10% and a coefficient of variation of 1-1.5%. See, Id.

Accordingly, the present disclosure relates to nutritional compositions including exogenous K2 and methods of making and using the nutritional compositions. The present disclosure also relates to the use of pQCT and DEXA to measure bone density and bone tissue micro architecture. Embodiments of the nutritional compositions of the present disclosure can promote the increase of bone density, mineralization and mechanical stiffness as well as improved bone tissue microarchitecture while minimizing potentially negative effects on blood coagulation and risk of bone fracture. Thus, the use of exogenous vitamin K2 may allow for increase bone health and its associated benefits in pediatric patients. Using pQCT and DEXA, as described above, it is possible to accurately measure bone density and bone microarchitecture to demonstrate the effects of the presently claimed nutritional compositions.

In a general embodiment, the present disclosure provides a nutritional composition including exogenous vitamin K₂. The nutritional composition may further include a component selected from the group consisting of phosphorus, magnesium, zinc, iron, copper, manganese, calcium, vitamin D, osteopontin and combinations thereof.

As used herein, the term “nutritional composition” includes, but is not limited to, complete nutritional compositions, partial or incomplete nutritional compositions, and disease or condition specific nutritional compositions. A complete nutritional composition (i.e., those which contain all the essential macro and micro nutrients) can be used as a sole source of nutrition for the patient. Patients can receive 100% of their nutritional requirements from such complete nutritional composition. A partial or incomplete nutritional composition does not contain all the essential macro and micro nutrients and cannot be used as a sole source of nutrition for the patient. Partial or incomplete nutritional compositions can be used as a nutritional supplement. A disease or condition specific nutritional composition is a composition that delivers nutrients or pharmaceuticals and can be a complete or partial nutritional composition.

The exogenous vitamin K₂ can be combined with other ingredients for promotion of bone growth and bone quality. For example, exogenous vitamin K₂ could work more effectively to support bone health in pediatric patients when used in combination with a component selected from the group consisting of phosphorus, magnesium, zinc, iron, copper, manganese, calcium, vitamin D, osteopontin and combinations thereof. Exogenous vitamin K₂ may also work more effectively to support bone health when used in combination with amino acids (e.g., leucine), protein with low sulfur-containing amino acid content, lipids (n3:n6), bioactive peptides, protease inhibitors, creatine, etc.

As used herein, a synbiotic is a supplement that contains both a prebiotic and a probiotic that work together to improve the microflora of the intestine.

As used herein, “normal bone growth” preferably includes: during childhood and adolescence bones are sculpted by modeling, which allows for the formation of new bone at one site and the removal of old bone from another site within the same bone. This process allows individual bones to grow in size (linear growth and circumferential growth) and to shift in space. During childhood bones grow because resorption (the process of breaking down bone) occurs inside the bone while formation of new bone occurs on its outer (periosteal) surface. At puberty the bones get thicker because formation can occur on both the outer and inner (endosteal) surfaces. The remodeling process occurs throughout life and becomes the dominant process by the time that bone reaches its peak mass (typically by the early 20s). In remodeling, a small amount of bone on the surface of trabeculae or in the interior of the cortex is removed and then replaced at the same site. The remodeling process does not change the shape of the bone, but it is nevertheless vital for bone health. Modeling and remodeling continue throughout life so that most of the adult skeleton is replaced about every 10 years. While remodeling predominates by early adulthood, modeling can still occur particularly in response to weakening of the bone.

As used herein, a “nucleotide” is preferably understood to be a subunit of deoxyribonucleic acid (“DNA”) or ribonucleic acid (“RNA”). It is an organic compound made up of a nitrogenous base, a phosphate molecule, and a sugar molecule (deoxyribose in DNA and ribose in RNA). Individual nucleotide monomers (single units) are linked together to form polymers, or long chains. Exogenous nucleotides are specifically provided by dietary supplementation. The exogenous nucleotide can be in a monomeric form such as, for example, 5′ Adenosine Monophosphate (“5′-AMP”), 5′-Guanosine Monophosphate (“5′-GMP”), 5′-Cytosine Monophosphate (“5′-CMP”), 5′-Uracil Monophosphate (“5′-UMP”), 5′-Inosine Monophosphate (“5′-IMP”), 5′-Thymine Monophosphate (“5′-TMP”) or a combination thereof. The exogenous nucleotide can also be in a polymeric form such as, for example, an intact RNA. There can be multiple sources of the polymeric form such as, for example, yeast RNA.

Nutritional products are preferably understood to further include any number of additional ingredients, including, for example one or more, vitamin, mineral, sugar, a pharmaceutically acceptable carrier, excipient, flavor agent, or colorants.

The term “protein”, “peptide”, “oligopeptides” or “polypeptide” as used herein is preferably understood to refer to any composition that includes, a single amino acids (monomers), two or more amino acids joined together by a peptide bond (dipeptide, tripeptide, or polypeptide), collagen, precursor, homolog, analog, mimetic, salt, prodrug, metabolite, or fragment thereof or combination. For the sake of clarity, the use of any of the above terms is interchangeable unless otherwise specified. It will be appreciated that polypeptides (or peptides or proteins or oligopeptides) often contain amino acids other than the 20 amino acids commonly referred to as the 20 naturally occurring amino acids, and that many amino acids, including the terminal amino acids, may be modified in a given polypeptide, either by natural processes such as glycosylation and other post-translational modifications, or by chemical modification techniques which are well known in the art.

K2 AND INFLAMMATION

The acute control of global rates of protein synthesis is predominantly executed at the level of translational initiation with the modulation of various eukaryotic initiation factors (elFs). The protein kinase referred to as the mammalian target of rapamycin (mTOR), which serves as a convergence point for signaling by growth factors and amino acids to the mRNA binding step of translation initiation is involved in modulation of the phosphorylation of the binding protein for the eukaryotic initiation factor 4E, i.e. 4E-BP1. It also acts to control the phosphorylation status of the 70-kDa ribosomal protein S6 kinase (S6K1). Modulation of these translation initiation events allows for more immediate control of protein synthesis and is responsive to changes associated with acute metabolic or nutritional alterations.

The canonical NF-κB pathway involves nuclear transport of a p65-p50 heterodimer. Activation of NF-κB occurs when IκBs are phosphorylated by the IκB kinase complex, leading to ubiquitination and degradation of IκB and nuclear translocation of the NF-κB dimer. Cytokines such as TNF-α are potent activators of the canonical NF-κB heterodimer, and this activation is associated with muscle protein loss.

METHODS

Male Sprague-Dawley rats (175 g) are kept on a 12-h light:dark cycle with food (Harlan-Teklad Rodent Chow, Madison, Wis.) and water provided freely. Animals are administered daily doses of vitamin K2 (MK-7) or saline (control) via oral gavage over 7 days. Stock solutions of vitamin K2 are prepared containing 3.5 g/L HCO-60 and 1 g/L of M&-7 in buffer A (0.15 M NaCl, 0.05 M Tris-HCl, pH 7.5). The K2 is dissolved by sonication during five pulses of 5 set with an amplitude of 6 pm. Solutions thus obtained are clear, homogeneous, and stable. Shortly before vitamin K administration the stock solutions are diluted five times with buffer A, leading to a final HCO-60 concentration of 0.7 g/L. Further dilutions (as required) are made with 0.7 g/L HCO-60 in buffer A. Each dilution step is followed by sonication as described above. In all cases vitamin K2 is administered to the rats in 0.5 mL samples, with either 25 or 50 microgram oral doses.

On the final day (Day 7), rodents are administered vitamin K2 and 2 hours later were given an IP dose of LPS (Escherichia coli serotype 0111:B4, L2630, Sigma) intraperitoneally (0.5 mg/kg of body weight). Four hours later animals are sacrificed.

Measurement of Protein Synthesis—The fractional rate of synthesis (Ks) is estimated from the rate of incorporation of radioactive phenylalanine into total mixed muscle protein using the specific radioactivity of serum phenylalanine as representative of the precursor pool. The actual time for incorporation of the radiolabeled phenylalanine into protein is taken as the time elapsed from injection until freezing of muscle in liquid nitrogen.

Analysis of mTOR Signaling to elFs—Gastrocnemius muscles are weighed and homogenized in 7 volumes of buffer containing 20 mM HEPES (pH 7.4), 100 mM potassium chloride, 0.2 mM EDTA, 2 mM EGTA, 50 mM sodium fluoride, 50 mM glycerophosphate, 0.1 mM phenylmethylsulfonyl fluoride, 1 mM benzamidine, 1 mM dithiothreitol (DTT), and 0.5 mM sodium vanadate. The remaining homogenate is centrifuged at 10,000× g for 10 min at 4° C. The resulting supernatant is combined with an equal volume of SDS sample buffer and then subjected to protein immunoblot analysis. Samples are analyzed for the phosphorylation status of 4E-BP 1 (Thr37) and ribosomal protein S6 (Ser 235/236), the anti-phosphospecific antibodies were obtained from Cell Signaling Technology, Beverly, Mass. Additionally, samples are analyzed for phosphorylated IKKα/β (Ser176/180; Cell Signaling Technology) and phosphorylated p65 (Ser536; Cell Signaling Technology).

RESULTS

Treatment of rodents with K2 results in a significant decrease in the rise of plasma TNF-a compared to LPS treated animals. Additionally, vitamin K2 results in a significant blunting of the drop in phosphorlyation for IKKα/β and NFαB p65 induction compared to LPS treatment. Finally, K2 abrogates the decrease in. 4E-BPI(Thr-37) and ribosomal protein S6 phosphorylation compared to LPS treatment along with a greater preservation of the fractional rate of mixed muscle protein synthesis under conditions of inflammatory sepsis.
